Digital platforms, often labeled as part of the "sharing economy", are becoming increasingly relevant to both the daily lives of private individuals and to researchers. As these tools are transforming various communities (of interest, place, practice and circumstance) to establish new forms of connection, welfare, labour and service, there emerge fundamental questions around the perils of creation and use. In response to this disruptive trend, this workshop brings together perspectives and cases from researchers and practitioners across various disciplines to interrogate how different forms of collaborative economy might be imagined and created based on the ethics and logic of care.
